In one embodiment of the present application, there is provided an intelligent charging device, as shown in fig. 1, including:

The intelligent charging device in the above embodiment provides a mechanical arm for carrying a charging plug, and the mechanical arm is connected with a power supply through a charging base. When the vehicle detection unit detects that the electric vehicle needs to be charged, a vehicle charging signal is generated, and the control system controls the mechanical arm to charge the vehicle based on the vehicle charging signal. The link that manual operation charges for the vehicle has been saved, and when the vehicle was located the distance scope that vehicle detecting element detected, control system can control the robotic arm and charge for the vehicle, and is intelligent simple and convenient, and charge efficiency is high, has effectively solved in the manual operation charging process because of being unfamiliar with the operation procedure, causes the maloperation easily, may cause charging device to damage, causes the electric leakage even and causes the problem that the user causes bodily injury etc..

Further, as shown in fig. 2, the intelligent charging device in the above embodiment is provided with a charging interface detection unit 12 on the mechanical arm, and the charging interface detection unit is connected with the control system and is used for detecting a charging interface of the vehicle. The charging interface detection unit 12 may be disposed at an outer side of the top end of the manipulator, and when detecting a charging interface of the vehicle, the charging interface detection unit may send position information of the charging interface to the control system, and the control system controls the manipulator to perform a predetermined action based on the position information of the charging interface, so that the charging plug 11 is inserted into the charging interface to charge the vehicle.

Specifically, in the intelligent charging device in the above embodiment, the charging interface detection unit 12 may adopt an infrared imager, for example, a feilel E53 advanced infrared thermal imager, E53 has a resolution as high as 43200 pixels, and a temperature measurement range can reach 650 degrees centigrade at most, which has an excellent distance coefficient ratio, and compared with a conventional infrared imager, E53 can realize accurate temperature measurement on a smaller target in a longer distance range, and can also utilize laser to assist automatic focusing to accurately identify a hot spot.

As shown in fig. 3, in an embodiment of the present application, the intelligent charging device further includes a charging current detection unit 14, which can be connected to the control system, for detecting whether the intelligent charging device is charging and detecting whether charging is completed. If the mechanical arm starts to charge after the charging plug is inserted into the charging interface, a charging current flows through an internal circuit connecting wire of the mechanical arm, the charging current detection unit 14 detects the charging current, and the charging current indicates that the charging is in progress, otherwise, the charging is not performed. When the mechanical arm inserts the charging plug into the charging interface to fully charge the electric vehicle, the charging current is stabilized below a small threshold value.

The indicating lamp is not lightened when the vehicle battery is fully charged, and the indicating lamp is lightened to inform people that the vehicle battery is fully charged. In this embodiment, if the charging current detection unit is connected to the control system, when the charging current detection unit detects that the vehicle is fully charged, the charging current detection unit may send a vehicle electric quantity full-charge signal to the control system, and the control system controls the mechanical arm to pull out the charging plug from the vehicle charging interface based on the vehicle electric quantity full-charge signal.
